If they're not self motivated, I have no incentive to use them.

No, not any. Just spamtrap based lists poorly administered.

Spamcop didn't provide much help. They were last on my list of dnsbls
to check, so they caught very little spam. I won't miss spamcop.
My three step defense works fine without spamcop:
1) require matching DNS, forward and reverse
2) use regex tests for dynamic/dialup host names (works because #1
strictly enforced, and thus hostname is known)
3a) query dynablock.njabl.org for any dynamic hosts missed by my local
checks in step 2
3b) query a few GOOD, RELIABLE dnsbls:
dnsbl.njabl.org
list.dsbl.org
sbl-xbl.spamhaus.org
With this defense, very little spam succeeds. All I get now are the
occasional stray spams sent by users of legitimate ISPs. The only way
to stop that is content filtering, and since the volume is negligible,
I don't bother.
